While we&#8217;re sipping champagne, they&#8217;re working overtime. <\/p><p>Research now shows that the Chinese hacker group DarkSpectre has been targeting the one piece of software we use constantly for almost everything: our browsers. For seven years, they&#8217;ve been infiltrating our browsers using extensions that seem useful at first glance. Think of tools for downloading videos, Zoom meeting assistants, or PDF converters.  <\/p><p>THE PROBLEM?<br>These extensions, just like apps on your phone, need access to everything that happens in your browser. This allows them to constantly monitor your activity, see what&#8217;s in your bank account, and harvest usernames, passwords, and session cookies on a massive scale. <\/p><p>At least 8.8 million users have already been compromised, and that number is growing daily. For hackers, our browsers are veritable Ali Baba&#8217;s Caves, filled with digital treasures and the keys to our personal and business data. <\/p><p>The scary thing is that this isn&#8217;t about a lone hacker in his parents&#8217; basement. This is an organized group playing the long game: they gather information, wait patiently, and then mercilessly attack the web applications you use. And well, MFA (Multi-Factor Authentication) isn&#8217;t going to save you here. These extensions are active both before and after authentication.   <\/p><p>WHAT SHOULD YOU DO NOW?<\/p><ul><li><strong>browser-hygiene first<\/strong>: Remove any extension you don&#8217;t explicitly trust. Do this on all browsers (including the Firefox you &#8220;almost never&#8221; use) and on your tablet. <\/li><li>factory reset (optional): Back up your bookmarks and completely reset your browser. Start with a clean slate. <\/li><li>limit your plugins: Be extremely critical. You can never be 100% certain whether a plugin is malicious, especially if the logic runs &#8220;in the cloud.&#8221; <\/li><li>for organizations: Ensure you have control over the software your users install. Implement a policy and enforce it technically. Additionally, you can shield the command-and-control domains used for harvesting on your DNS server or firewall, but that&#8217;s a bit more complex.  <\/li><\/ul><p>Staying safe isn&#8217;t a product you buy; it&#8217;s a continuous process of attention and resilience. This also applies to your browser. Any comments, additional information, or tips? Feel free to leave them in the comments.  <\/p><p>Need help becoming cybersecure and, more importantly, resilient?
